"Cyclic deformation behavior and fatigue life of squeeze-cast AZ31 magnesium alloy was studied under stress amplitude-control at room temperature. Low and high cycle fatigue tests with engineering stress amplitudes in the range from 40 to 110 MPa were conducted. Analysis of hysteresis curves was performed. Tension\u2013compression asymmetry of hysteresis loops was not observed; the alloy exhibited cyclic hardening in tension and compression. The fatigue life in the low cycle fatigue region was expressed by W\u00F6hler and derived Manson\u2013Coffin curves. Experimental data in both, the low and high cycle fatigue regions were fitted by means of regression functions. S\u2013N curves exhibited a smooth transition from the low to the high cycle fatigue regions and significant scattering of experimental points was observed.
